Right-angled slotted link 1 turns about fixed axis A and has two slots a whose axes are perpendicular to each other. Pins b of links 2 and 3 slide along slots a of link 1. The diameter of the pins equals the width of the slots. When slotted link 1 turns about axis A, links 2 and 3 are displaced in opposite directions. Displacement y₃ of link 3 equals y₃=k*tan(α), and displacement y₂ of link 2 equals y₂=d*cot(α), where α is the angle of rotation of link 1. Thus the mechanism simultaneously generates two functions: tan(α) and cot(α).
